LATE EARLY

Common Name Glaziovi's Habenaria [French Gardener, Head of Rio Botanical Garden 1800's]

Flower Size 5/8" [1.5 cm]

Found on roadside banks and rocky fields in most all States of Brazil as a medium sized, warm to cool growing terrestrial with an erect, thin stem enveloped by elongate-linear to linear-lanceolate, acuminate, three nerved, basally clasping leaves that blooms in the fall on an erect, 1.6 to 2.8" [4 to 7 cm] long, 7 to 12 flowered inflorescence with wide-lanceolate, long-acuminate, shorter than the ovary floral bracts.

+This species is very similar and undoubtedly close related to H. pratensis (Salzm. ex Lindl.) Rchb. f. The main difference is the width of the midlobe of lip and petal posterior segment, which are very broad and expanded in H. glazioviana and narrower in H. pratensis (midlobe of lip 9-22 mm wide vs. ca. 2-5 mm wide in H. pratensis). In the coast restingas of northeastern Brazil the two species can occur side by side and the existence of intermediate forms makes identification difficult. Further studies are still necessary to determine the exact relation between the two taxa. Flowers are pale yellow and the species is usually found in seasonally humid places

Synonyms Habenaria odorifera Hoehne 1915; Rhinorchis glazioviana (Kraenzl. ex Cogn.) Szlach. 2012
